Is mass spectrometry analysis performed on oligonucleotides before they are shipped?

Every oligo manufactured by IDT is analyzed by mass spec as part of our quality control (QC) assessment. The oligos must satisfy QC requirements before they can be shipped. Mass spec traces are available in customer online accounts under "Order History".
